METAL BUILDING WALL CONSTRUCTION. I

Specification of Letters Patent.

Patented Dec. 18, 1917.

Application filed August 14, 1916. Serial No. 114,923.

To all whom it may concern:

Be it known that I, ALLAN K, PRUDEN, a citizen of the United States, and a resident of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Metal- Building Wall Constructions, of which the following is a specification.

One object of my invention is to provide in a. wall construction for a metal building an insulation to prevent heat readily passing through the wall from either direction.

Another object of my invention is to provide in a metal wall, having metal studs formed therein, means for attaching insulating board thereto.

Another object of my invention is to provide in a metal wall construction having metal studs therein, means for attaching thereto double insulating boards with air spaces between the units comprising sald double board.

With these and incidental objects in view, the invention consists of certain novel features of construction and combination of parts, the essential elements of which are hereinafter described with reference to the drawing which accompanies and forms a part of this specification.

In the drawing, Figure 1 is a perspective view of a portion of a wall of a metal building showing my preferred construction applied there Fig. 2 is a section taken on the line A A, Fig. 1.

Fig. 3 is a similar section showing a modification of my wall construction and Fig. 4

is a similar section showing a still further modification of my wall construction.

The metal wall 1, Fig. 2, which is described in my Patent #1008491, dated Nov. 14, 1911, com rises units 2, joined together at 3 and having in the center of each unit a fold 4 which is in efi'ect a metal stud for the structure.

Vertical furring strip 5 having a slot 6 therein which registers with the stud 4 clamps to the metal wall 1 a wall board 7 of any suitable material.

The furring strip is preferablyfastened to the stud 4 by bolts 8 spaced at suitable distances along its height so the building may be readily dismounted.

An inner wall board 9 or ceiling of any suitable material is nailed by nails 10 to the furring strip, thus f0 an insulated wall which comprises the outer metal sheet 1, air space 11, insulatingboard 7,1air space 12, and insulating'board 9, thusgiving almost perfect insulation.

It will be noted that no metal extends through the Wall, so there are no heat conducting portions "connecting the outer and inner surfaces of the wall.

In place of the construction shown in Fig. 2,. I sometimes use that shown in Fig. 3 in which the wall board 7 is held to the wall 1 by a sealing plate 13 formed at 14 to register with the studs 4 to which it is fastened by the bolts 8.

This construction gives an inner and outer metal wall with an insulating board 7 and an air space 11.

Instead of either bf these two constructions, I also sometimes employ the construction shown in Fig. 4, in which the wall board 7 is held to the sheet 1 by the T shaped flanges 15 bolted to the studs 4 by bolts 8 in which case the wall has the outer metal sheet 1, the air space 11, and the wall board 7.

By sealing the wall construction at the bottom and top, I am able to produce an absolutely air-tight wall and one that is insulated suitably for any climate by the construction shown in Fig. 2 and for the milder climatic conditions by the. constructions shown in Figs. 3 and 4.

While I have described my invention and illustrated it in several particular construe! tions, I do not wish it understood that I limit myself to 'these constructions, as it is.

evident that the application of my invention may be varied in many ways within the scope of the following claims.

Claims: 1 I I 1. In a wall construction for metal buildings, the combination of an outer metal wall comprising unit plates having interloch'ng joints, a metal 'stud formed from each of said units and extending inwardly therefrom, wall board associated with said outer metal wall and positioned between two adjacent studs, and means associated with each of said studs for clamping said wall board to said outer metal wall.

2. In a wall construction for metal buildings, thecombination of an outer metal wall comprising unit plates having interlocking joints, a metal stud running longitudinally of each of said unit plates formed from said plates and extending inwardly therefrom,

intermediate of said interlocking joints, wall board units associated with said metal wall, each wall board unit being positioned between adjacent studs and means associated with each of said studs for clamping said wall board to said metal Wall.

3. In a wall construction for metal buildings, the combination of an outer metal wall, a stud extending inwardly from said wall, a wall board insulation, a furring strip having a slot therein registering with each of said studs, and means for clamping said furring strips to saidj studs thereby holding said wall board in fassociation with said metal wall.

4. In a wall construction for metal buildings, the combination of an outer metal wall, a stud extending inwardly from said wall, a wall board insulation, a furring strip having a slot therein registering with each of said studs, means for clamping said furring strip to said studs thereby holding said wall board in association with said metal Wall, and a wall board fastened to the inner surface of said furring strips 5. In a wall construction for metal buildmo em ings, the combination of an outer metal wall comprising unit plates having interlocking joints, a metal stud formed from each of said studs, thus holding said wall board in association with said metal wall.

6. In a wall construction for metal buildings, the combination of an outer metal wall comprising unit plates having interlocking joints, a metal stud formed from each of said units and extending inwardly therefrom, a wall board associated with said outer metal wall and positioned between two adjacent studs, furring strips having slots therein registering with said studs, means for locking said furring strips to said studs, thus holding said wall board in association with said metal wall, and a Wall board fastened to the inner surface of said furring strips.
